Well Rohan, it looks to be the same fibre glass as the Norton side cover I have but near all the parts (except generic) looked to be Triumph so thought it might be off the same being put in with the rest.
It came with many Lucas
switch blocks, perches, levers, a lot of AMAL
parts, maybe 20 lbs of mostly Triumph Fasteners
so not sure it would be off a Honda
There was so much good stuff (on closer inspection) I sent the 'older gentleman I purchased it off another payment.
The top picture is the mold side and the resin and pin holes are visible in places, I don't recall seeing anything of that construction on a Brit car either.
